Hi all,
I get a NoClassDefFoundError for com.google.gwt.core.client.GWTBridge when
I throw a RuntimeException on a server RPC. When I do not throw the
RuntimeException and the RPC completes fine also no NoClassDefFoundError is
thrown.
As a workaround, I created an abstract com.google.gwt.core.client.GWTBridge
which simply extends the ...shared.GWTBridge class. I read about
http://code.google.com/p/google-web-toolkit/issues/detail?id=7527 but it
seems that this is something different, or not? Any solution?
Cheers,
Moritz.
PD, here comes the full stack trace, the exception seems to be related to
the Guice filters:
